Global Sea Levels Will Rise Quicker Than Thought -- Study (NZHerald.co.nz)

Fears that global sea levels this century may rise faster and further than expected are supported by a study showing that 300 glaciers in Antarctica have begun to move more quickly into the ocean.
Scientists believe that the accelerated movement of glaciers in the Antarctic Peninsula indicates a dramatic shift in the way melting ice around the world contributes to overall increases in global sea levels.
Instead of simply adding huge volumes of meltwater to the sea, scientists have found that rising temperatures are causing glaciers as far apart as Alaska, Greenland and now Antarctica to break up and slip into the ocean at a faster rate than expected.
The findings are likely to raises concerns within the UN's Intergovernmental Panel on Climate Change (IPCC) which earlier this year downplayed the so-called "dynamic" nature of melting glaciers - when rising temperatures cause them to break up quickly rather than simple melt away slowly.
